ON many newer GM vehicles, the low coolant light is controlled by a module that is on the radiator. It has 3 wires and is usually below the radiator neck. Look for it.

Also, I would go to www.alldatadiy.com and get a subscription for your Truck, its very reasonable. That way you will have pictures and all the info that you need. Then you will know.
